Answer 1

in week 8

Answer 2

how did you figure that out @britbrat4290

Answer 3

X + 4Y = 32
3X + 10Y = 84

(-16/-2 , -12/-2)........(8 , 6).....My own method I teach my students

Mult by 5.......5X + 20Y = 160........20Y = 160 - 5X
Mult by 2.......6X + 20Y = 168........20Y = 168 - 6X

160 - 5X = 168 - 6X..........Add 6X

160 + X = 168...................Subtract 160

X = 8

ANSWER in week 8
